Former big leaguer Jose Canseco waxes poetic about comet landing

The combination photo of different images taken with the CIVA camera system released by the European Space Agency ESA on Thursday Nov. 13, 2014 shows Rosettaâs lander Philae as it is safely on the surface of Comet 67P/Churyumov-Gerasimenko, as these first CIVA images confirm. One of the landerâs three feet can be seen in the foreground. Philae became the first spacecraft to land on a comet when it touched down Wednesday on the comet, 67P/Churyumov-Gerasimenko.

Former big league slugger Jose Canseco has been watching the historic Rosetta comet mission very, very closely.

At least he was for four intense minutes on Thursday, during which he tweeted about the landing of a robotic device known as Philae on the rump of comet 67P/Churyumov-Gerasimenko after a 10-year, 4-billion-mile journey, no less than six times.
